摘　　要：基于三层结构 (馈电缝、耦合缝、辐射缝 )平面缝隙阵天线设计的需要 ,用场分析法对由耦合纵缝馈电的两端短路波导宽边直线纵缝阵进行了分析和综合。该法考虑了所有的互耦、高次模及波导壁厚的影响 ,得到了耦合纵缝馈电的两端短路波导宽边纵缝直线阵在辐射缝偏心距相同和缝长相同时直线缝阵口径分布等幅同相的结论。Based on the need for the design of planar arrays with three layer structure(feeding slot, coupling slot, radiating slot),the theoretical analysis and synthesis of slot fed longitudinal slots in a broad wall of a rectangular waveguide with shorted terminals is presented. During the analysis and synthesis of the array, the fundamental integral equations that describe the array are used directly. Mutual coupling between slots, higher order mode and finite waveguide wall thickness are included as integral parts of the development. The results of the synthesis are presented to illustrate the advantages of the new method for the synthesis of the slot array in a rectangular waveguide with shorted terminals .
